Default create excel file without excel.exe

Hello,

I want to create an excel file from all the data gathered in my application. The problem I have is that Excel is not installed on my PC so creating the xls file by means of communicating with Excel.exe (OLE, ActiveX, ...) is not an option.


Installing Excel on the PC also isn't an option since the PC's are used inside a production environment and installing Excel on every PC would simply cost too much.

So, in short, I'm looking for code/examples/dll's/third party toolkits that allow me to create an excel xls file from within my application.


Thanks in advance for all the help!

While I am pretty sure that you cannot create a native xls format file without having excel, at least you can do it easily, you can create a csv (Comma Seperated Values) file that excel can read easily. However, if you must have the native format, see http://www.wotsit.org/list.asp?search=xls



Good Luck

That sounds more like a problem between versions of excel but without seeing the code that causes the problem I can only guess...



Good Luck

Okay,... on your machine, design it as you have but before you compile it, change your code to use CreateObject (see your friends, yahoo, google, ask, answers, bing for "vb6 createobject excel application"). It is a simple enough change to make and also you will have to remove the reference to excel before you compile. Also, add error trapping to catch the error if it is unable to create the excel application object. If that is successful then pretty much everything else should be successful unless you have used something that is not a part of a previous version of excel and the machine your program is on has that previous version.



Good Luck

As vb5prgrmr has said, CSV files are the best option. You can save the CSV file as ".XLS". When the user opens it he needs to save a copy in Native Excel format

The best option would be to go for OpenXML and create Excel (.xlsx) file as an XML file through code
